		@Brooke LigertWood - We attended your ​concert on March 21st in Naperville Illinois
		The concert was simply ruined for us by the reverb or bass being excessively loud. It is harmful to people with health issues.
		Loud noises like excessive reverb at a concert can cause atrial fibrillation https://www.healthline.com/health-news/loud-noises-bad-for-your-health#Your-hearing-takes-a-hit


I am following your CKAD course and I am confused about Volumes, Mount Path and Volume mounts.
I have Windows11 with WSL2.
In  C:\Users\AP\Documents\Projects\regular-encourager>
I type wsl
I get
/mnt/c/Users/AP/Documents/Projects/regular-encourager
1) Is Windows mounted in Linux or is Linux mounted in Windows?
2) What is the mount point?
3) In the kubernetes yaml files, should I put the Windows path or the Linux path?
4) Is "name" an alias for the mount point?
----multi container pod-----
spring boot runs in /app
therefore if logging.file.name=../tmp/regular-encourager.log
then the log will be found in /app/tmp

I am following your CKAD course and I am confused about Volumes, Mount Path and Volume mounts.
You asked me to email you but I did not get a reply.
I have Windows11 with WSL2.
1) In the kubernetes yaml files, should I put the Windows path or the Linux path?
2) Is "name" an alias for the mount point?

--------------
@Sander, All morning I have been experimenting with running different values for the mount point. Only the Windows value /mnt/c/mydir works.for me. Can you please explain how to find the value of the NFS  path as you mentioned?

my app (spring boot) logs are written to

root@regular-encourager-69667cc897-8bjpv:/app# ls -l logs
total 4
-rw-r--r-- 1 root root 3301 Mar 24 17:50 quotes.log
